Centers for Medicare & Medicaid Services

Minnesota Attorney General Lori Swanson says a federal investigation is needed to look into business practices at one of the nation’s largest private Medicare insurers. On Friday, Swanson sent a massive file of complaints against Humana to the federal agency charged with overseeing that part of Medicare. She’s asking the Centers for Medicare & Medicaid Services (CMS) to look into more than 27 complaints on file.
